Authorities say a Polk County man charged with sharing child pornography committed suicide. Polk County Medical Examiner Gregory Schmunk said Monday that 48-year-old Paul Thomas Hildreth fatally shot himself in the head. Polk County Sheriff's deputies found Hildreth's body Sunday at a rural Polk City home. Hildreth was charged last month with sharing two images of nude underage girls. Hildreth told police he wasn't involved in producing child pornography, but he was charged with sexual exploitation of a minor. Investigators found 1.5 million images on two of his computer hard drives and children's toys and video games in his basement.
